Maximum Heater Exposure The Maximum Heater Exposure temperature is the maximum temperature to which the heating cable may be exposed intermittently. The Minimum Ambient temperature for indoor locations should be the lowest indoor temperature irrespective of the minimum outdoor temperature. Minimum Ambient The Minimum Ambient temperature is the lowest temperature expected at the pipe location. This will result in a higher actual temperature. The Maintain temperature must be greater than the Minimum Ambient temperature as there is no need for heat tracing if the Minimum Ambient temperature is greater than the Maintain temperature. The effect of wind for outdoor locations is considered in the design. Maximum Ambient The Maximum Ambient temperature is the highest temperature expected to occur at the design location. The Maximum Ambient temperature is typically used to calculate the maximum uncontrolled pipe temperature and when necessary. with total cumulative exposure of less than 1000 hours. Heat loss calculations are based on the Minimum Ambient temperature. the heating cable selected will provide more heat than is required to hold the pipe at the Maintain temperature. At higher temperatures. In many applications the Maximum Heater Exposure temperature will be the same as the Maximum Operating temperature. This value must be greater or equal to the Minimum Ambient temperature. Defined as high-temperature excursions of not more than 48 hours in duration. TraceCalc Pro User Guide H57159 (05/03) 5 Designing Your Project • 43 . to determine whether a hightemperature cut-off thermostat is required. Heat-loss calculations depend on the difference between the Minimum Ambient temperature and the desired Maintain temperature. The Maximum Ambient temperature for indoor locations should be the highest indoor temperature irrespective of the maximum outdoor Ambient temperature. The program checks the Minimum Ambient temperature to ensure that it is less than the Maintain temperature and less than the Maximum Ambient temperature. TraceCalc Pro must have information about the following temperatures: Maintain The Maintain temperature is the desired temperature at which you want to maintain the pipe by the use of heat tracing. This temperature is ignored for the purpose of predicting maximum heating cable sheath temperatures. This is reported in the Calculated Results Pane. The program will calculate the Uncontrolled Temperature of the pipe assuming Maximum Ambient temperature and no wind.Temperatures For a complete design and product selection of a heat-tracing system. The wind chill factor should not be used. The value you enter should be the lowest value of the fluid degradation temperature. this is the actual voltage applied to the heater. All “Child” line types will inherit the Electrical settings from their Parent. Excursions of less than 1000 hours may be ignored. Maximum Allowable The Maximum Allowable temperature is the maximum temperature permitted by the user for the process/ fluid or piping. For example. This voltage affects which heating cables may be selected. the maximum temperature ratings are entered separately as an auto-ignition temperature and T-rating. The Maximum Operating temperature may be the same as the Maintain temperature. or the piping material withstand temperature (especially in the case of plastic piping). For Single phase systems and Three phase DELTA systems. this should be the phase-to-phase voltage. but it could be considerably higher. TraceCalc Pro will select a suitable heating cable assuming that the Maximum Operating temperature is the highest continuous (for greater than 1000 hours) exposure temperature for the heating cable whether energized or de-energized (depending on the control method). and their maximum circuit lengths. this value will be calculated by dividing the Voltage by the square root of 3. Heater Operating Voltage This is a read only field where TraceCalc Pro displays the calculated voltage that is assumed to be applied to the heating element. (Note: the Electrical section is only active when you are editing a “Parent” line type. the Maintain temperature is only slightly above the freezing temperature of the fluid. For hazardous locations. Please see “Design Parameters” on page 50. For Three phase WYE (Star) systems.Maximum Operating The Maximum Operating temperature is the highest temperature of the heat-traced fluid during normal process operating conditions. when a process pipe operates at a high Operating temperature but the heat tracing is only required to prevent the pipe from freezing during shutdown conditions. In this case. Electrical You need to enter certain electrical data for each line so the program can make the correct product selection. For 3 Phase systems. TraceCalc Pro then calculates the actual voltage appliced to the heater and displays it in the Heater Operating Voltage field. 44 • 5 Designing Your Project H57159 (05/03) TraceCalc Pro User Guide . Voltage For Single Phase systems. this value will be the same as the entered Voltage. The program uses temperature to determine whether temperature controls are required.

Adhesive-backed aluminum tape allows better dissipation of heat and is often used on plastic pipes. The Channel option is often used on pre-insulated piping. by checking this box. Self-regulating heating cables will generate more power when installed with aluminum tape than when installed with glass tape due to improved heat transfer. The method used to attach a heating cable to a pipe or vessel can affect the heat output of the heating cable. When a selfregulating heating cable is used in a channel. you allow the program to more closely balance the heat provided to the heat required by specifying the degree to which the heating cable should be spiraled. Banding or tie wires are typically used with metal sheathed heating cables and are not appropriate for cables with polymer insulation.Design Options Manual Select Attachment Check the Manual Select Attachment box to view the list of attachment methods available for selection. the program will select an appropriate method by default.

The following are descriptions of cables based on these two technologies: • • Parallel Circuit Series Circuit Parallel Circuit Self-Regulating Heating Cables: Self-regulating heating cables are the preferred choice for most complex pipe-tracing applications. The heating element is made of polymers mixed with conductive carbon black. This contraction decreases electrical resistance and creates numerous electrical paths between the bus wires. As a result. Current flows across these paths to warm the core or fiber. As the ambient temperature surrounding the heating cable decreases. In heating cable core the number of electrical paths between the bus wires changes in response to temperature fluctuations. the core or fiber expands microscopically. Self-regulating heating cables are based on conductive-polymer technology in both monolithic (solid core) and fiber-wrap heating cable designs. This is due to their parallel construction. TraceCalc Pro User Guide H57159 (05/03) 7 Heat-Tracing Technologies • 81 . This special blend of materials creates electrical paths for conducting current between the parallel bus wires along the entire cable length. the conductive core or fiber contracts microscopically. As the temperature rises. and the number of electrical paths decreases. This expansion increases electrical resistance. the heating cable automatically reduces its power output. the insulation is removed alternatively. This distance between contact points forms the heating zone length. first from one of the bus wires and then from the other. This technology can provide a cost-effective alternative to self-regulating heating cables when more than a single run of cable is required (trace ratio > 1). Power-limiting cables are parallel heating cables formed by a coiled resistor alloy heating element wrapped around two parallel bus wires. These cables can be used for high maintain temperatures ranging up to 455°F (235°C) depending on cable selection and exposure temperatures to 482°F (250°C).Power-Limiting Heating Cables: Power-limiting heating cables are the preferred technology for applications requiring high power output at elevated temperatures. 82 • 7 Heat-Tracing Technologies H57159 (05/03) TraceCalc Pro User Guide . At a fixed distance. This effect allows the power-limiting cable to be crossed over itself since the temperature of the heating element is reduced at the cross over points. TraceCalc Pro User Guide H57159 (05/03) 7 Heat-Tracing Technologies • 83 .The positive temperature coefficient (PTC) of the heating element reduces power output as ambient temperature increases. MI heating cables provide superior strength in dynamic cut-through. please refer to local product literature. MI is the ideal choice when an application’s temperature and power output requirements exceed the capabilities of self-regulating and powerlimiting heating cables.Series Circuit Mineral Insulated (MI) Heating Cables: Mineral Insulated heating cables offer a wide variety of solutions for industrial pipe and equipment heat-tracing applications. MI heating cables can be used for applications with the following requirements: • • • Maintain temperature up to 1022°F (550°C) Maximum heating cable exposure temperature to 1238°F (670°C)* Power output to 82 W/ft (269 W/m) * Higher temperatures are available upon manufacturer’s approval MI heating cables consist of one or two conductors embedded in a highly dielectric magnesium oxide insulation surrounded by a metal sheath. crush. Special annealing processes maximize flexibility for ease of on-site handling. 84 • 7 Heat-Tracing Technologies H57159 (05/03) TraceCalc Pro User Guide . MI heating cable sets are supplied factory terminated and ready to install. MI heating cables are series-type heating cables and suitable for maintain temperatures up to 1022°F (550°C) and/or exposure temperatures for the heating cable to 1238°F (670°C). Various constructions are available in different market places. and corrosion tests. For detailed information. They include a heating section and a cold lead (nonheating) section. polymer-insulated heating cables can be used when the circuit length required exceeds that permitted by parallel-circuit heating cables. please refer to local product literature.Polymer Insulated Heating Cables: Series constant-wattage. Polymer-insulated heating cables can be used for applications with the following requirements: • • • Maintain temperature up to 356°F (180°C) Maximum heating cable exposure temperature to 500°F (260°C) Maximum power output to 9 W/ft (30 W/m) Various constructions are available in different market places. TraceCalc Pro User Guide H57159 (05/03) 7 Heat-Tracing Technologies • 85 . They incorporate a fluoropolymer outer jacket that makes them ideal for chemically aggressive applications.
